Tree of Codes by Jonathan Safran Foer is a new story carved out of Jonathan's favourite book, The Street of Crocodiles by Bruno Schulz. And when we say carved out, we really mean carved out: every single page in this book has a different die-cut. There's nothing out there quite like it, as far as we know. Tree of Codes is as much a new reading experience as it is a tactile, even sculptural one.
